How can I output the rundifference as a positive number no matter in which order I enter

HomeTeamName=(input("Home Team Name:  "))
HomeRuns=int(input("Home Runs: "))

AwayTeamName=(input("Away Team Name:  "))
AwayRuns=int(input("Away Runs: "))
WinningTeamName=0
RunDifference=0

RunDifference=HomeRuns-AwayRuns


if HomeRuns>AwayRuns:
   HomeTeamName==WinningTeamName
   print("Winning Team was{0}, who scored {1}more runs".format(HomeTeamName, RunDifference))

else:
     AwayTeamName==WinningTeamName
     print("Winning Team was  {0} , who scored  {1}  more runs".format(AwayTeamName, RunDifference))
